Smoking Marijuana With A Water Bong Doesn’t Effectively Filter Compounds From Smoke, Study Suggests

Published
2 days agoon

For decades, marijuana consumers have debated whether using a bong, where smoke is pulled through water before inhalation, is any safer than inhaling smoke from a joint. Conventional wisdom has long held that water filtration makes for a cleaner, less harmful consumption experience.
But a new study, by authors affiliated with the University of Wisconsin-Madison and in Thailand, concludes that “bong water does not seem to significantly filter out any compound from the smoke.”
For the study, researchers analyzed the chemical makeup of smoke from three popular cannabis strains—Bubble Gum, Silver Haze and Hang Over OG—when consumed through both joints and bongs. Using gas chromatography-mass spectrometry (GC-MS), a highly sensitive apparatus that identifies chemical compounds by their molecular weight, they looked for differences in the final combusted smoke.
The results for both consumption methods were nearly identical. Bong water didn’t completely remove any of the detected compounds in the range the instrument could measure. The study found no compounds that appeared only in joint smoke and not in bong smoke, suggesting the water did not fully capture any components within the tested size range.
Gas chromatography-mass spectrometry “results from both the bong and joint smoke show similar smoke composition. No compounds between 5 to 350 g/mol were completely filtered by the bong water.”
The researchers note in the paper, published as a pre-print on bioRxiv, that their methods couldn’t capture larger particles, aerosols or metals—in other words, things that water might catch. Still, the findings cast doubt on the idea that a bong meaningfully reduces exposure to harmful chemicals.
“Although the effectiveness of the filtration of the bong is not clear, this study sheds light on the chemical composition of cannabis smoke,” they concluded.
The study also shows promise for compounds detected in higher concentrations. They note that the prevalence of β-cis-Caryophyllene, which was consistently present in the highest quantities, suggests “possible physiological importance despite limited research compared to THC and CBD.” They added that the compound “has a potential anti-inflammatory, antibiotic, antioxidant, anticarcinogenic and local anesthetic activity.”
The researchers argue that one of the biggest obstacles in cannabis science is the lack of standardized tools to measure what’s actually in smoke. Tobacco research, by contrast, relies on decades of standardized methods that make it possible to compare cigarettes across brands and countries.
“Establishing standardized analytical approaches could support more accurate assessments of cannabis quality, health risks, and therapeutic potential, while enabling comparisons across strains, cultivation methods, and global research efforts,” they wrote.
The authors caution about the methodological constraints, including sample size and smoke loss during collection. The Agilent GC-MS was limited in its ability to “detect larger particles, aerosols, and metal ions, restricted definitive conclusions regarding bong filtration effectiveness. However, the findings highlight that cannabis smoke contains a reproducible profile of compounds, both harmful and potentially beneficial,” they wrote.
The researchers stress that more standardized methods—such as better ways of measuring larger aerosols and analyzing the bong water itself—will be needed to draw firmer conclusions.
The study has not been peer reviewed. Additionally, the authors recently withdrew the paper “because there may be a conflicting bureaucracy issue due to the location this research was performed,” an update on the bioRxiv website says.
Bong water became a topic of policy interest in the U.S. when the Minnesota Supreme Court ruled in 2009 that it could be legally considered a drug, in part due to a state patrol officer testifying that marijuana users keep bong water “for future use…either drinking it or shooting it in the veins.” The state law changed this year when legislators and the governor enacted a law that ended the risk of decades in prison over drug residue.
Minnesota’s unique law came into national spotlight in 2024 when a Fargo woman faced the possibility of a 30-year prison sentence after being caught with bong water. The charges caused the Minnesota ACLU to represent her, given the draconian nature of the prosecutor’s actions.

The Toking Traveler: Why Amsterdam Weed Is Mostly Boof

Published
13 hours agoon
September 14, 2025
You know those tequila shops in Mexico? The tourist traps in every major resort town that try to pass off random blends of grain spirits as the real-deal Holyfield blue agave tequila?
Yes, this may come as a shock to our audience, but if you have even the slightest sense of what defines a quality cannabis product, you may leave Amsterdam feeling a bit… hoodwinked. Bamboozled. Punk’d.
Firmly the mecca of cannabis since back in 1976, Amsterdam holds a special place in our stoner hearts because of their laissez-faire approach to recreational consumption. For many, a trip to their famed coffee shops was the first chance we had to legally get high. White Widow, AK-47, OG Kush…they seem to have all the classics, along with a laundry list of different Hazes (e.g, Amnesia Haze, a signature smoke of the Dutch).
On my most recent trip back in July, I stepped off the plane after a particularly hellish 20+ hour journey from LA to Istanbul before finally reaching Schiphol and beelined for The Bulldog, arguably the most famous coffee shop in existence. While I appreciated the conversations I had with other patrons and staff alike, including a gregarious German home grow enthusiast living on an isolated island in the Caribbean, only in town while on his way to Eastern Europe for “the REAL Dracula history tour, not the one you see in guides,” the caliber of social interaction doesn’t really make up for how subpar their cannabis is.
Imagine an OG Kush that doesn’t look like OG, doesn’t smell like OG, or even hit you like OG. Yeah, it’s even more of a gutpunch after you realize you dropped $18 on a single gram of it.
Do the Dutch simply not care about quality? Or perhaps they mix so much damn tobacco into their spliffs that it doesn’t matter?
In my travels, I met many locals who also bemoaned their city’s lack of quality. This all stems from the fact that the Dutch have adopted a “tolerance policy,” as while cannabis (and other substances) do remain federally illegal in the Netherlands, they’ve realized that attempting to regulate often does more harm than good. Who’d have thought?!?
While there is essentially zero enforcement around the use of “soft drugs”, such as cannabis and psilocybin truffles, the rest of the supply chain is a fragmented nightmare of backroom deals and questionable practices. Simply stated, it’s all illicit market product.
Their system is entirely built around rewarding the lowest cost of production, regardless of safety or standards. Any cannabis you’ll find in Amsterdam hasn’t been lab tested, meaning that harmful bacteria, pesticides, and who knows what else are likely present in your bag. They’re able to get away with it, as most of the tourists crawling the Red Light District will never return to that same shop. It’s designed to run efficiently and without accountability.
Case in point:
- It is illegal to possess or use cannabis.
- It is illegal to commercially grow cannabis.
- It is legal for coffeeshops to sell you cannabis, but not for them to acquire that cannabis, so it “magically appears” for sale at each location.
Curious, eh? This is also why there is a very high probability that your coffee shop cannabis was grown on the top floor of a local high-rise apartment building by an organized criminal syndicate (and yes, they own/operate the rest of the space to provide cover). Your OG isn’t true OG because there are no repercussions if it’s not.
Now, the one exception where you can find true-to-strain cuts seems to be most of the Haze cultivars, as these are massively popular in Europe (and thus with locals) and known for being premium quality, so the bar is often a bit higher.
Fortunately, the times they are a-changin’ and even a craft rosin scene has started to develop in the city. I was personally blown away by the service I received at Boerejongens, a coffee shop that the headiest of locals kept endorsing. Outside of their shop, I was greeted by an employee in a sharp bowler hat and three-piece suit. These guys serve as de facto guardians of the neighborhood community, helping to ensure that anyone visiting doesn’t get too unruly. They’ll even help little old ladies cross the street or provide expert-level guidance to anyone lost, customer or otherwise. Inside the store, the “hipster barista” meme has been taken to wholly new levels, as there was a row of budtenders decked out in white butchers’ aprons, wielding giant butchers’ knives to chop up flower into your desired quantities. The Strawberry Haze at Boerejongens ran circles around everything else I procured, outside of a decent Blueberry Haze I found near Vondelpark.
Next time you’re ready to enjoy a toke as you navigate Amsterdam’s canals, do yourself a favor and avoid the touristy areas like the plague. The further you’re away from the Red Light District (and I’m sad to say, shops like The Bulldog), the closer you are to finding buds that won’t just scratch your itch but will truly impress you.

Arkansas Medical Marijuana Sales Are On Track To Set A New Annual Record

“A total of $1.5 billion has been spent on medical marijuana since the state’s first dispensary opened in May 2019.”
By Sonny Albarado, Arkansas Advocate
Arkansans spent $10 million more on medical marijuana so far this year than during the first eight months of 2024, putting the state on track to exceed a record set two years ago, according to the state finance department.
From January through August, Arkansans bought $193.1 million in medical marijuana products from the state’s dispensaries, compared with $182.5 million in the same period last year, according to a press release from the state Department of Finance and Administration.
“With daily sales averaging about $800,000 in 2025, we are on track to surpass the 2023 sales record of $283 million,” department spokesperson Scott Hardin said.
There has also been a significant year-to-year increase in the number of pounds of cannabis sold, Hardin said, with the 2025 total at 52,292 pounds.
The state collected $5.38 million in tax revenue from medical marijuana in July and August, bringing the total tax haul so far this year to $21.57 million.
Patients spent $24,262,201 in July, purchasing 6,721 pounds, and $24,647,170 in August, buying 6,778 pounds, according to the finance department.
Suite 443 in Hot Springs and Natural Relief Dispensary in Sherwood sold the most medical marijuana in both July and August, according to the press release. Suite 443 sold 1,419.6 pounds total for both months. Natural Relief sold 1,317.7 pounds over July and August.
“A total of $1.5 billion has been spent on medical marijuana since the state’s first dispensary opened in May 2019,” Hardin said.
The Arkansas Department of Health reports 109,060 active patient cards. The Medical Marijuana Commission has licensed 38 dispensaries but only 36 are operating, Hardin said. The license of one of the closed dispensaries was revoked by the state Alcoholic Beverage Control Board last year, and its owner’s appeal of the revocation remains before the courts.

When Cannabis Brands Blur Into Youth Culture, Regulators Notice: Lessons From Tobacco’s Past

Published

September 13, 2025
TL;DR: Cannabis is meant to be enjoyable for adults. But when products start looking like candy or cartoons, the line gets blurry. Tobacco’s history shows that even the appearance of marketing to kids can trigger harsh regulations. If cannabis wants a sustainable future, it has to prove it can draw that line for itself.
Cannabis has always been fun. It is part of what makes it powerful, what makes it stick in culture. But fun becomes a problem when it starts creeping into the territory of kid-friendly. That is the line the industry needs to pay attention to, now more than ever.
History has already shown what happens when that line gets crossed. Big Tobacco learned it the hard way: even the appearance of marketing to children is enough to trigger a backlash that can reshape an entire industry.
The Ghost of Joe Camel
Once upon a time, tobacco companies leaned hard into youth culture. Joe Camel, candy cigarettes, neon packaging, and bubblegum-flavored smokes were all part of the playbook. By the early 1990s, research showed that six-year-olds recognized Joe Camel almost as easily as Mickey Mouse. Camel’s share among underage smokers soared.
The public response was swift. By 1998, the Master Settlement Agreement banned cartoons in tobacco ads, restricted sponsorships, and wiped Joe Camel off the map. The lesson was clear: once the public believes you are targeting kids, you do not just lose credibility, you lose control over your own marketing future.
Cannabis’ Candy Problem
Today, echoes of that playbook are showing up again. In 2023, the FTC and FDA issued joint warning letters after finding THC edibles packaged to mimic Skittles, Oreos, Nerds Rope, Doritos, and Cheetos. Regulators deemed the practice reckless and illegal, since children could easily mistake these products for ordinary snacks.
In California, a 2025 state audit found that more than half of the reviewed cannabis products had packaging “likely attractive to children.” Designs included colorful fonts, cartoon mascots, and labels that mimicked cereals and cookies.
These incidents are not about strangers handing out weed candy on Halloween. That myth has been debunked year after year. The real risk, one that does occur from time to time, is more ordinary: a toddler at home finding a bag of gummies that looks exactly like the treats they already know and love.
Flavors, Fonts, and Lifestyle Crossovers
Packaging is only part of the story. Visit a legal dispensary and you will see products with candy-like flavors and bright, playful labels. As Columbia University epidemiologist Katherine Keyes noted, “If you go through a cannabis dispensary right now, it’s almost absurd how youth-oriented a lot of the packaging and the products are.”
On the other hand, the lifestyle layer adds another wrinkle. Some cannabis brands have leaned into culture so thoroughly that their logos appear on streetwear, music videos, and even kids’ clothing lines. Whatever the intent, the optics are tricky. When children wear cannabis-branded merch, even innocently, it normalizes adult practices in youth culture.
On social media, the risks multiply. A 2022 study of dispensary posts found that six percent featured cartoon characters like SpongeBob or Rick and Morty, while more than a third advertised steep discounts. These are old marketing tricks recycled from alcohol and tobacco, and for a reason: they still work.
The Regulatory Lens
In the US, states are already tightening their grip. Colorado banned edibles shaped like animals or fruit, and requires a universal THC symbol on every piece of candy. New York’s cannabis regulations forbid packaging or ads “designed in any way to appeal to children.” California has barred cartoons, neon fonts, and fruit imagery on labels.
At the federal level, agencies are also stepping in. The FTC and FDA crackdown on copycat edibles showed regulators do not need cannabis to be federally legal to act. And in Congress, the issue is already in debate. In 2025, Senate leaders cited hemp-derived gummies marketed like Oreos and cereals as justification for closing the intoxicating hemp loophole. Senator Mitch McConnell called it “deceptive and predatory marketing towards children.”
If cannabis continues down this path, federal legalization could arrive paired with harsh restrictions: plain packaging mandates, advertising bans modeled on tobacco, or a blanket prohibition on flavors. As things stand, the industry risks trading creativity for a regulatory straightjacket.
Walking the Line
The situation may seem dire, but let’s remember: cannabis is not Big Tobacco. It does not need to be. Nevertheless, perception is powerful: if the industry does not draw a clear line between adult fun and kid-friendly branding, others will draw it for us.
The choice is simple: either the industry proves it can self-regulate, or Congress and regulators will do so with a heavy hand.
Cannabis has a chance to write a different story. A responsible story. One that keeps products creative and culture-rich without turning them into candy-colored billboards for kids. That is how the industry earns trust, protects its future, and avoids being treated like the enemy it never wanted to be.
